Lateral ankle sprains from sports are the primary cause of posttraumatic ankle osteoarthritis, often leading to varus malalignment. Chronic instability may persist in end-stage ligamentous ankle osteoarthritis.

Area of Science:

  • Orthopedics
  • Sports Medicine
  • Biomechanics

Background:

  • Ankle sprains are the most frequent sports-related injuries.
  • Ankle ligament injuries can lead to the development of ankle osteoarthritis.
  • The time between injury and osteoarthritis onset varies with ligament type and location.

Purpose of the Study:

  • To investigate the causes and characteristics of ligamentous end-stage ankle osteoarthritis.
  • To determine the latency period between ankle ligament injury and osteoarthritis development.
  • To explore correlations between ligamentous lesions, hindfoot alignment, and persistent instability.

Main Methods:

  • Retrospective case series analysis of 30 patients with end-stage ankle osteoarthritis.
  • Etiological, clinical, and radiological evaluations were performed.

  • Data included injury history, latency time, hindfoot alignment, and ankle arthritis grade.

    • Main Results:

    • Sports injuries caused 55% of ligamentous lesions, with soccer being prevalent.
    • Lateral ankle ligaments were most commonly injured (85%).
    • Mean latency to osteoarthritis was 34.3 years; single severe sprains had shorter latency than chronic lesions. Medial sprains had shorter latency than lateral sprains. Varus malalignment (52%) and persistent instability (52%) were common, correlating with chronic lateral instability.

    Conclusions:

    • Lateral ankle sprains are the primary cause of posttraumatic ankle osteoarthritis.
    • Varus malalignment is associated with end-stage ligamentous ankle osteoarthritis.
    • Persistent instability is a common finding in patients with end-stage ligamentous ankle osteoarthritis.
